GroupInterventionDescription
PanobinostatPanobinostatParticipants with metastatic hormone refractory prostate cancer received 20 milligrams per meter square (mg/m\^2) of panobinostat intravenously (i.v.) on Days 1 and 8 of a 21-day cycle. Treatment continued until disease progression as per investigator, intolerable toxicity, start of new cancer therapy, death, or withdrawal of consent.
Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Progression-Free Survival (PFS) Rate at 24 Weeks24 weeks

The PFS rate was defined as the percentage of participants that were alive without documented disease progression at the end of 24 weeks from first study treatment. Disease Progression as per response evaluation criteria in solid tumors (RECIST) criteria: Measurable lesions: If target lesion was lymph node then it had to be at least 2 centimeter (cm) at baseline to assess change in size. Bone lesions: (non-target lesions) appearance of greater than or equal to (\>=) 2 unequivocal new lesions confirmed on a second scan at least 6 weeks later.

Secondary Outcome Measures
NameTimeMethod
Overall SurvivalStart of study treatment to date of death due to any cause (Up to approximately 2.7 years)

The overall survival was defined as the time from date of start of treatment to date of death due to any cause. If a participant was not known to have died, survival was to be censored at the date of last contact. Kaplan-Meier method was to be used to estimate overall survival.

Median Progression-free Survival (PFS)After every cycle up to approximately 2.7 years

PFS was defined as the time from the date of start of treatment to the date of first documented disease progression or death due to any cause. If a participant had not had a disease progression and was alive, the participant was to be censored using the RECIST. Disease Progression as per RECIST criteria: Measurable lesions: If target lesion was lymph node then it had to be at least 2 cm at baseline to assess change in size. Bone lesions: (non-target lesions) appearance of \>=2 unequivocal new lesions confirmed on a second scan at least 6 weeks later. Kaplan-Meier method was to be used to estimate the median PFS.

Percentage of Participants With Tumor Response RateEvery 12 weeks up to approximately 2.7 years

The tumor response rate was defined as a percentage of participants with confirmed Complete Response (CR) or Partial Response (PR) per RECIST criteria. CR: Disappearance of all target lesions and all nontarget lesions. PR: At least a 30% decrease in the sum of the longest diameter of all target lesions, taking as reference the baseline sum of the longest diameters.

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)From start of the study up to at least 4 weeks following the last dose of study treatment (Up to approximately 2.7 years)

An AE was an adverse medical event which occurs in a participant of the study and which is not necessarily in a causal relationship with the treatment the participant receives. SAEs were AEs leading to death, are life-threatening, require hospitalizations or prolongation of hospitalizations, represent an innate malformation or a congenital abnormality.

Percentage of Participants With Duration of Stable Disease (SD) Per RECISTEvery 12 weeks up to approximately 2.7 years

Duration of SD was the time from date of start of treatment to the date of event, defined as the first documented disease progression or death due to underlying cancer. Disease Progression as per RECIST criteria: Measurable lesions: If target lesion was lymph node then it had to be at least 2 cm at baseline to assess change in size. Bone lesions: (non-target lesions) appearance of \>=2 unequivocal new lesions confirmed on a second scan at least 6 weeks later. SD: Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for PD. CR: Disappearance of all target lesions and all nontarget lesions. PR: At least a 30% decrease in the sum of the longest diameter of all target lesions, taking as reference the baseline sum of the longest diameters. If a participant had not had an event, duration of SD was to be censored at the date of last assessment.

Percentage of Participants With Prostate Specific Antigen (PSA) Response Rate at 24 Weeks24 weeks

The PSA response was defined as a 50% decrease in PSA from baseline maintained for \>= 4 weeks, and without clinical or radiographic evidence of disease progression during this time period. Disease Progression as per RECIST criteria: Measurable lesions: If target lesion was lymph node then it had to be at least 2 cm at baseline to assess change in size. Bone lesions: (non-target lesions) appearance of \>= 2 unequivocal new lesions confirmed on a second scan at least 6 weeks later.

Percentage of Participants With PSA Progression Rate at 24 Weeks24 weeks

The PSA progression was defined as a 50% rise from nadir and a minimum rise of 2 nanogram per milligram (ng/mL). Disease Progression as per RECIST criteria: Measurable lesions: If target lesion was lymph node then it had to be at least 2 cm at baseline to assess change in size. Bone lesions: (non-target lesions) appearance of \>=2 unequivocal new lesions confirmed on a second scan at least 6 weeks later.
